Abstract

The invention discloses a cross-linked film blow molding device which comprises a machine head, the machine head is connected with an extruder at the bottom, a shaping channel is formed in the bottom of a shaping frame, the cross-linked film blow molding device further comprises an air conveying channel, the air conveying channel is formed in the center of the machine head in a penetrating mode, and an air blowing cylinder is installed above a guide cylinder; the top of the machine head is fixedly provided with an air guide ring seat, and the top of the sealing plate is connected with a tooth roller; the screw rod is installed at the top of the air blowing cylinder, the screw rod is sleeved with a shaping frame in a threaded mode, limiting racks are fixed to the front side and the rear side of the shaping frame correspondingly, a main gear and an auxiliary gear are installed in an embedded bearing in the installation frame, and a movable rack is arranged below the auxiliary gear in an engaged mode; the herringbone clamping plate is located in the mounting frame. According to the blow molding device for the cross-linked film, the film is uniformly blown up, the film is prevented from being deformed, meanwhile, automatic traction can be carried out, and troubles caused by manual traction are avoided.

Description

technical field [0001] The invention relates to the technical field of cross-linked film blowing, in particular to a cross-linked film blowing device. Background technique [0002] The blow molding of the cross-linked film is to extrude and melt the material through the extruder, and then export it from the blow molding channel in the machine head and inflate it through the internal high-speed air flow, cooperate with the cooling and forming of the external phoenix ring, and then pass through the blow molding. The splint is used for shrinking and guiding and subsequent winding of the formed film, but the existing cross-linked film blowing device has the following problems in use: [0003] During the molding process of the film, the inner diameter is much larger than the outer diameter of the high-speed compressed air blown out from the middle, resulting in uneven force on the film during the inflation of the compressed air mass, which is prone to deformation, and it is incon...
